Primality proof for n = 52060951900024830751:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=532731547.html>532731547 is prime.</a>
<br>b^((n-1)/532731547)-1 mod n = 20868794780281631884, which is a unit, inverse 26187975940538776833.
<p><a href=10023031.html>10023031 is prime.</a>
<br>b^((n-1)/10023031)-1 mod n = 25235745741590589850, which is a unit, inverse 29134923866134425413.
<p>(10023031 * 532731547) divides n-1.
<p>(10023031 * 532731547)^2 > n.
<p>n is prime by Pocklington's theorem.
